fix(deploy): provisioning aborts on every non-manager host, and the failure summary hid it (#17240, #17242, #17243, #17244) - #17241
Merged
Conversation
…nts as hosts (#17240) A two-host provisioning run reported '3 hosts failed', naming the same host three times. Two defects in _extract_failure_summary, both operator-facing. Ignored failures were counted. A task with ignore_errors: true still prints a full 'fatal:' line and only then '...ignoring'; the parser keyed on the 'fatal:' prefix alone. This is the normal first-provision path, not an edge case: both marker reads in roles/_shared/tasks/sync_deletions.yml are ignore_errors: true because a host with nothing deployed yet has no marker to read, so every first run emits two ignored failures and the summary always reported them. The one real failure was buried among them. The count was of failure events, labelled as hosts. 'failures' holds one entry per 'fatal:' line, so one host failing three tasks read as three hosts -- on a two-host run, more hosts than exist. Host and failure counts are now separate, and differ in the headline only when they actually differ. The existing multi-failure test could not catch either: it uses two hosts with one failure each, so the two counts coincide and the conflated variable reads correct. Added four tests that discriminate -- several failures on one host, an ignored failure excluded, an all-ignored run yielding no summary at all, and a real failure not being silenced by the NEXT task's '...ignoring'.

✅ SSOT Configuration Compliance: Passing🎉 No new hardcoded values of either class — Known backlog in |
…17242, #17243, #17244) code_source is the controller's git checkout and no task syncs it to a node, so a task that executes out of it on the target exits 127 on every host that is not the manager. It passed for as long as the manager was the only backend host -- there the controller and the target are the same machine -- and aborted the first time a second host joined the group. #17242 backend role: the filtered-requirements script now runs on the controller via delegate_to, reading the manifest from code_source rather than from the target, and the result is written into the backend tree. Carrying it in a registered variable also removes /tmp/requirements-filtered.txt -- a fixed name in a world-writable directory that every host would have collided on the moment this task moved to the controller, so delegating alone would have traded one bug for a racier one. #17243 four more of the same shape: - ai-stack role: same script, same omission, in a role that never runs on the manager at all. Generated on the controller from the manifest path the deploy task above it already uses. - update-all-nodes Play 2 (hosts: infrastructure), three pip steps constrained against code_source/constraints/shared.txt. The file is now staged onto the node and the constraint points at the local copy. Play 1 (hosts: slm_server) keeps its code_source reference -- the manager has it, and repointing it there would have broken a task that was never broken. - record_slm_deployed_commit.yml: delegated, matching sync_deletions.yml, which has always delegated the identical rev-parse. Two shared tasks doing one operation should not disagree about where it runs. #17244 backend_ai_stack_host asked only "is this WSL2", never "is the AI stack on this node". Its sibling twelve lines below has always asked role_ai_stack_active; the two disagreed. Now it asks too. Behaviour is unchanged whenever the stack is not on this node, which is the case #3503 fixed. Guard: repo_tests/ansible_code_source_delegation_17243_test.py fails when a target-side executing module reads code_source without delegate_to, exempting plays pinned to the controller or manager by scope rather than by name. Verified by mutation -- against the pre-fix tree it reports exactly these 6 sites; against this tree, 0. It also carries a reach floor, so a walk that stops matching fails instead of passing vacuously. CI does not execute Ansible, so none of this is observable before a fleet node hits it. Verified here: YAML parses on all four files, the guard's own mutation check, and every play scope re-derived rather than assumed.

browser-worker to both the constraints directory task and the
constraints/shared.txt staging task, preserving their existing behavior so they
run whenever any dependent selector is chosen.
In `@autobot-slm-backend/ansible/roles/backend/tasks/main.yml`:
- Line 60: Replace the hardcoded WSL2 addresses in the backend_ai_stack_host
expression with role-default variables, defining defaults for both active and
inactive AI-stack routes so inventory can override them. Preserve the existing
role_ai_stack_active selection behavior and boolean handling.
- Around line 977-983: Stage the CUDA torch, faiss, and vLLM requirement
manifests under backend_code_dir alongside the filtered requirements, then
update the corresponding GPU pip tasks to read those staged files instead of
root-level code_source_dir paths. Preserve the existing GPU and
backend_vllm_enabled conditions while ensuring all three manifests are copied
before use.
In `@autobot-slm-backend/services/ansible_utils.py`:
- Line 120: Update the loop scanning subsequent lines in the helper around the
displayed range to continue through len(lines) rather than stopping after 40
positions, so it reaches the semantic ...ignoring boundary despite long or blank
YAML result sections. Add a regression test covering more than 40 non-empty
result lines before ...ignoring and verify ignored fatal events are excluded
from the failure summary.
In `@repo_tests/ansible_code_source_delegation_17243_test.py`:
- Line 125: Add an executable contrast pair for
test_no_target_side_task_reads_code_source_undelegated: provide isolated YAML
fixtures or a parameterized scan helper containing one undelegated target-side
task that _offenders() reports and an equivalent controller-delegated task that
it ignores, asserting both outcomes.
- Line 102: Update the task filtering condition around task.get("delegate_to")
to exempt code_source tasks only when delegation explicitly targets an approved
controller destination such as localhost, rather than any truthy value. Add
contrasting fixtures and assertions covering controller delegation and dynamic
or non-controller delegation, ensuring the latter remains detected.
- Line 105: Update the scope check in the test’s controller-scope detection
logic to compare the normalized scope as a complete value against
_CONTROLLER_SCOPES, rather than using substring matching; preserve the existing
handling for None and ensure compound or dynamic scopes remain offenders.

1 of 4 tasks
#17240, #17242, #17243, #17246) CI red on shard 8/12 -- both failures mine, both meta-guards doing their job. glob_declared_reads_15900: the new guard rglobs *.yml and was not registered in the record of which guards read which glob. Registered. ansible_manifest_resolution: the ai-stack binding read as 'nothing installs it'. Cause: that resolver follows a manifest through write-edges formed ONLY by a '> OUTPUT' redirect or a copy: with a real src:. Passing the filtered content through a registered variable created neither, so the chain broke. Both the backend and ai-stack tasks now use the redirect-then-copy shape the resolver can follow, with a per-host filename so the shared /tmp collision this PR set out to remove stays removed. Chains verified: the pip target resolves back through the controller temp to the repo manifest in both roles. The ai-stack source also moved off {{ playbook_dir }}, which that resolver deliberately cannot resolve because its depth depends on the including playbook. CodeRabbit findings, all seven valid: - staging tasks were untagged, so --tags backend|npu|browser|deps would skip them and leave pip constraining against a file that is not there. Tagged 'always', which this play already uses, rather than a union of consumer tags that would go stale when the next consumer is added. - three GPU pip tasks read root-level manifests out of code_source. Staged, one task per manifest: a loop renders dest as a template the resolution guard cannot tie to a manifest. - the WSL2 addresses are now role defaults, and the shipped default is named once so the override can ask 'is this still the default?' without restating it. - the ignored-failure scan ran to a fixed 40 lines; under the yaml callback a result is longer than that, so it could stop inside one result and report an ignored failure as real. It now runs to the result boundary. - delegate_to was accepted when merely truthy; 'delegate_to: {{ inventory_hostname }}' still runs on the fleet host. Only controller destinations exempt now. - play scope was matched by substring, so 'backend,localhost' was exempt. Exact per-token matching now. - the detector had no contrast pair. Five fixtures added, each with a known answer: offending, delegated, controller-scoped, fake-delegate, mixed-scope. Widening the detector to pip -- which CodeRabbit's GPU finding exposed -- shows the class is 16 sites, not 6. Ten were invisible because the first sweep listed modules by how they run rather than by what they do with a path. The seven that remain are pre-existing and recorded in _KNOWN_UNSTAGED so this guard blocks new instances now; the list can only shrink, and a stale entry fails the build. Tracked by #17246.
… repo_root (#17243) Three more CI reds, all mine. SSOT Configuration Compliance blocked two new hardcoded values: the staging paths began /tmp/autobot-, and HV_AUTOBOT_PATHS in scripts/lib/hardcoded-value-rules.sh matches /tmp/autobot literally. Renamed to /tmp/requirements-*.<host>.txt, the shape the pre-existing path already used, keeping the per-host uniqueness that removes the shared-name collision. test_deploy_constraint_rewrite_14272: a role that copies a requirements file must install the filtered output, not the raw copy -- a file copied out of the repo lands at a different depth, so relative -c/-r includes resolve elsewhere. The three GPU manifests carry no such include today, so this costs nothing now and is correct if one is added. They now go through the same canonical filter as every other manifest. one_repo_root_spelling_15925: the new guard re-derived the repository root from __file__ instead of calling repo_tests._paths.repo_root().
… wrapper (#17231, #17241) Folded in from two separate PRs rather than run as their own CI. Splitting them cost a full suite each for a two-line docs fix and a config block, and queue depth is what was actually delaying the fix that matters. docs/research/_index.md: main is red on test_every_research_document_is_reachable_from_its_index with 'present but unindexed'. #17231 added the document and never added its index row -- the exact drift that test was written for, missed when landing that PR. Base breakage, so every open PR inherits it. .coderabbit.yaml: the review on this PR produced seven findings and all seven were valid -- three were real bugs in code written that hour, and one exposed a detector blind spot that turned a six-site defect class into sixteen. So profile: assertive stays and no finding is suppressed. What is switched off is the per-comment wrapper: the AI-agent restatement, sequence diagrams, effort estimate, suggested labels/reviewers, and related issues/PRs. Keys checked against the published schema first, so each line is a real change and not a no-op. The 'Supported by static analysis' blocks are the other bulky part and the schema exposes no key for them.
…e cheap (#17241) Every red on this PR was a repo-wide guard: a convention encoded in a check I did not know existed. Not one was a logic bug. tools/lint/prepush_selection.py selects 'a changed test runs itself; a changed module runs its co-located foo_test.py'. A guard that scans the tree is co-located with nothing, so no change ever selects it and its first signal is CI. Four cycles went that way on this PR alone. Two rules added, both derived rather than guessed: Glob-declared guards. A changed path now also selects any guard declaring a matching glob, read out of the #15900 record as DATA via ast -- not imported, because that module pulls in pytest and imports from this package, so importing it back would close a cycle. The record is already CI-enforced to stay accurate, so this cannot rot quietly. Guards that police guards. A changed repo_tests/*.py selects the two that enumerate every tracked file. Named rather than sniffed: 45 guards import tracked_paths and running all of them on every push costs most of a shard, while the heuristics that narrow that set do not cleanly isolate these two. exists() drops a renamed entry, so the list fails open rather than blocking a push on its own staleness. Replayed against this PR's four pytest reds: 4/4 would now fail at pre-push instead of in CI. Cost is 27 static guards for one ansible edit, against a full suite and a push/fix cycle. Seven tests, including the contrast case (a path matching no glob selects nothing), the scope case (a non-guard change does not drag in the guard police), the fail-open case, and an unparseable record degrading to {} instead of breaking every push.
shard 11: backend_gpu_torch_gating and backend_gpu_faiss_gating assert the
install task points at requirements-gpu-torch.txt / -faiss / requirements-gpu.txt
by substring. Naming the staged copy requirements-gpu-torch-filtered.txt broke
that substring -- the manifest name no longer appeared in it.
Renamed to filtered-<manifest>.txt instead of <manifest>-filtered.txt, so the
original name survives intact and those guards keep checking what they were
written to check. Weakening the assertions to accept a variant was the other
option and the worse one: they exist to prove the task installs THAT manifest.
Applied to the backend and ai-stack staged files too, for one naming rule rather
than three. That also makes a near-miss robust: test_deploy_constraint_rewrite
collects copy sources whose basename starts with 'requirements' and ends '.txt',
so the old names were kept out of its offender set only by the
{{ inventory_hostname }} sitting in the middle. Starting every staged name with
'filtered-' removes the coincidence.
Verified statically before pushing, using the selection added in the previous
commit to find which guards these files reach: every pip target still resolves
through its staged copy back to a code_source manifest, the four substring
assertions hold, and the one copy source that still starts with 'requirements'
is the pre-existing repo-manifest deploy that the guard's own test requires to
be there.
Written by another session and left untracked because the branch freeze blocks a branch of its own. Folded in here rather than given one: the same reasoning as the last research doc, and the owner's rule that a problem found while a PR is open rides that PR. The conclusion is a negative and worth keeping as one: the inventory cannot offset development token spend -- wrong API, wrong account, and 1-3 orders of magnitude short on quota -- and integration value is near zero because adapters already exist for 5 of its 16 providers and the rest are OpenAI-SDK-compatible config. What it did expose is three governance gaps in our own LLM path, which are filed as #17248 and its children. Indexed in the same commit. A research document that is not in _index.md turns doc_sync_hook_resolves_indexer red for every open PR -- that is exactly how #17231 broke main earlier today, and adding the row here is the whole of that lesson. Verified before committing: 0 URLs, 0 domains, no source repository or author reference, and 14/14 file:line citations resolve -- one was ambiguous (manager.py:28 matches eight files) and is now qualified to services/provider_health/manager.py.
code-quality red: scripts/lint-conventions.sh:200 requires every docs/research/*.md to name an issue, because an umbrella-scale document that cites none cannot be traced to the work it produced. The doc was written to be self-contained and cited nothing. Added a Filed section naming #17248 and its children rather than a bare reference, and stating why #17249 is not a duplicate of #17233 -- the two measure different populations, and LLM providers are a third bucket that reaches the network through vendor SDKs, so #17233's ruling would not reach them. Citations re-verified after the edit: 14/14 resolve.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winUse the configured WSL2 loopback host for ChromaDB.
The default
backend_chromadb_hostfollowsbackend_ai_stack_host, so overriding onlybackend_wsl2_loopback_hostdoes not by itself leave the default ChromaDB value at127.0.0.1.

…4809, #17242) shard 5: test_requirements_are_not_delivered_twice asserts the ai-stack task file names ai-stack/requirements-ai.txt exactly once, because a second reference used to be a second delivery that landed too late to help. The filter step added for #17242 has to name the manifest too, so the count became 2. The filter's reference is a controller-side READ, not a delivery, but the guard counts occurrences and cannot tell the difference -- and weakening it to distinguish them would trade a cheap invariant for a subtle one. So the copy task now takes its source from a role default and the task file keeps a single literal, in the filter step. Defining it against code_source_dir rather than playbook_dir is a second small win: ansible_manifest_resolution deliberately cannot resolve playbook_dir, whose depth depends on which playbook included the role. Verified before pushing: literal count 1; deliver(15) < filter(17) < install(19) so the ordering guard still holds; and the manifest chain still resolves filtered-requirements-ai.txt <- the staged copy <- requirements-ai.txt.
…5707) The restored pre-push hooks blocked on one_repo_root_spelling_15925::test_no_guard_binds_the_repo_root_by_hand. That guard ast.parses every repo_tests file, and provision_playbook_path_agrees_15707 carries `\s*` in a non-raw docstring, so parsing it emits an invalid-escape warning that the run treats as a failure. Pre-existing and untouched by this branch -- identical on origin/main. It surfaced now because the pre-push selection added in this PR runs the guards-that-police-guards whenever a repo_tests file changes, and this branch adds one. The selector working as intended, on a defect that was already there. Only visible locally: this interpreter is python 3.10, where an invalid escape is a DeprecationWarning; CI runs 3.14, where the same text is a SyntaxWarning and the shard has been green. The hook prints that the environment sits below 104 of 209 declared floors and that a pass here says nothing about CI -- the same caveat applies to a failure, which is why this is fixed rather than treated as a CI signal. Fixed rather than bypassed. --no-verify is not an option, and the escape is a real latent defect regardless of which interpreter notices it.
…lter (#14809, #14272) Two guards constrain the same line and pull opposite ways: #14809 test_requirements_are_not_delivered_twice -- the ai-stack task file must name ai-stack/requirements-ai.txt EXACTLY once. #14272 test_the_copy_scan_sees_the_ai_stack_role -- _copied_requirements() reads the copy task's src BASENAME and keeps it only when it starts with "requirements", so the copy's src must be the literal path. My previous commit satisfied the first by moving the copy's src to a role default, which emptied the second's scan and turned its "would this rule pass vacuously?" control red. Both hold only if the one permitted literal sits in the copy. So the copy keeps the literal and the filter step, which merely reads the manifest on the controller, takes the role default instead. Verified before pushing, all four at once: literal count 1; the copy scan sees requirements-ai.txt; deliver(15) < filter(17) < install(19); and the manifest chain still resolves filtered-requirements-ai.txt <- the staged copy <- {{ ai_stack_requirements_src }} <- a code_source path, with the pip target named filtered-* so the raw-install rule stays satisfied. Caught by pre-push, not CI.

#17226) The last of the three untracked research documents, and the only one that was actually at risk: 564 lines existing in no branch, local or remote, one `git clean` from gone. The other two were already safe -- one merged via #17231, one already in this PR. Verified before committing, the same drill the previous two got: - Anonymisation. 0 source URLs; the two domain-shaped hits are our own issue link and Jan.ai, an inference backend we integrate. Two verbatim passages of the source's own copy were paraphrased -- a quoted marketing sentence is a searchable fingerprint, which is the finding that came back on #17231's review. Short generic product terms and the author's own scare-quotes stay. - Citations: 33/33 resolve. Three did not and were wrong in the ambiguous direction rather than the absent one -- two `main.py` references resolved to a 47-line file of that name, and a bare `defaults/main.yml`. All three were correct once qualified; confirmed by reading the cited lines. - Indexed in the same commit, so doc_sync_hook stays green. Its own substantive finding is already filed: ansible/roles/dependency_patching/ is fully implemented -- venv backup, 7-day retention, a rollback playbook -- and invoked by nothing (#17226).
…#17257) The row I added for the offline-first analysis credited its dependency_patching finding to #17226. That issue is "air-gapped operation is not a mode" and says nothing about the rollback role. The document attributes the finding to no issue at all -- I invented the number, which is the one error class this repo treats as serious, and I introduced it in the same commit that claimed 33/33 citations verified. The citation gate checks file:line coordinates; it does not check that an issue number means what the prose says it means. Corrected to #17257, filed now because the finding was not tracked anywhere: ansible/roles/dependency_patching/ is fully implemented -- venv backup, 7-day retention, a rollback playbook -- and referenced by no api module, no service module, and neither update playbook. An unwired rollback role is worse than ordinary dead code: it reads as a safety net that exists and is absent at the moment it would be used.
…ate (#15560) shard 9: ansible_backend_path_defects_15560 renders every templated value in the ai-stack defaults against the other defaults, under strict undefined. My ai_stack_requirements_src referenced autobot.base_dir -- an inventory group_var, not a role default -- so it raised UndefinedError there and took five tests with it. Replaced with ai_stack_requirements_rel, a plain relative tail with no Jinja at all, composed at the call site as {{ code_source_dir }}/{{ ai_stack_requirements_rel }}. Nothing to render, nothing to be undefined. Re-verified all five constraints together rather than one at a time, since this line is now load-bearing for four separate guards: 1. #14809 literal count in tasks/main.yml: 1 2. #14272 copy scan sees requirements-ai.txt 3. ordering deliver(15) < filter(17) < install(19) 4. every templated ai-stack default renders under strict undefined -- mine is no longer templated; the two that still fail (ollama_host, ai_redis_host, both on ansible_host) are pre-existing on main and predate this branch 5. the manifest chain still ends at requirements-ai.txt
All four were valid. 1. Controller temp files collided across runs (Major). Each generate/copy pair named its file with inventory_hostname alone, so two runs for the SAME host share it and the later generation can replace it before the earlier copy reads it. I had called per-host "good enough" while noting this very case; it was not. Ten paths across two roles now carry a per-run id, set once per host so the generate step and the copy that reads its output agree. 2. glob_declared_guards aborted the hook on a wrong-shaped record (Minor, but the blast radius is every push). It degraded on SyntaxError and not on valid Python of the wrong shape, where literal_eval succeeds and .items() or the tuple unpack then raises. This helper exists to fail open. Now validated shape by shape and verified against six inputs: real record, list, wrong inner shape, empty tuple, syntax error, absent key. 3. The free-LLM doc's header claimed Phase 1 only while its body recorded the comparison approved the same day. Header corrected. 4. The ai-stack copy and filter name the manifest through two independent expressions (Major). They must: #14272 reads the COPY's src basename so that src needs a literal filename, while #14809 allows the task file exactly one `ai-stack/requirements-ai.txt` so the filter needs a variable. Neither side can take the other's form, so the shape is forced and a code change would re-break one of them -- I did exactly that earlier in this PR. The real risk is drift under an override, so that is what is now pinned: repo_tests/ai_stack_manifest_agreement_17242_test.py. That guard was wrong on first write and the mutation check is what found it. It scanned for any token naming the manifest and picked the redirect TARGET, whose tail is ".txt" -- which every path ends with, so it passed against anything. It now takes the script's first argument. Verified both ways: passes here, catches a manifest renamed in defaults.

#17142) shard 12: the floor sat at 6507 with a tolerance of 401 (growth 400 + skips 1), and the live population is 6909 -- 402 above it, so it failed by exactly one file. The pin was measured at 6907; this branch adds two guard files (ansible_code_source_delegation_17243, ai_stack_manifest_agreement_17242). Re-pinned to population minus growth, the formula the other pins in this file use: 6909 - 400 = 6509, leaving the skips=1 as headroom. This is the #17142 shape again and the file's own comment block is a log of it: eighth re-pin of this floor, fifth where each change measured correctly alone and only collided once combined. Recorded in that log rather than silently bumped, because the pattern is the useful part -- a floor 400 from red absorbs roughly a week of growth, so any branch adding guards lands on it. Raising a reach FLOOR is the stricter direction and is allowed: it asserts the sweep must reach MORE files. That is the opposite of a size ceiling, which may only ever come down -- the distinction this repo draws deliberately, and the one I applied earlier in this PR when knowledge_population.py had to be split rather than have its ceiling raised.
4 tasks
…issue (#17241, #17257) The important one first. Review caught that this PR's research doc, the index row and **the issue I filed from it** all said the dependency_patching role was "invoked by nothing". That is false: it is invoked by four playbooks -- patch-dependencies.yml (four times), rollback-dependencies.yml, patch-system-packages.yml, rollback-system-packages.yml. The claim came from greps scoped to api/*.py, services/*.py and two named playbooks -- a scope that could not contain the answer -- and I filed #17257 from it without verifying the negative myself. Second time today I published something evidence-shaped that no automated check could contradict, and this one is worse than the wrong issue number: it asserted a fact about the codebase. Corrected in all three places, to the finding that survives and is narrower: nothing RUNS those playbooks. No service, API route or scheduled task references them, and update-all-nodes.yml does not include the role, so dependency rollback is reachable only by hand. Real, but a smaller claim than the one I made. The rest of the round: - The ai-stack filter used bare {{ code_source_dir }} while the copy applied a fallback, so a role running without it would copy fine and fail to filter. The same expression is now used at all four sites. It cannot be hoisted into a role default -- a templated default referencing autobot.base_dir is what broke shard 9 earlier in this PR. - The agreement guard compared only the tail after the last `}}`, so a copy rooted at one variable and a filter rooted at another matched. It now compares the whole resolved path. - That guard also had no contrast pair, so nothing proved it still discriminates. Two fixtures added with answers known by construction: matching references pass, diverging ones fail. - A regex inside a markdown table cell split the row on its alternation pipes. Escaped; all rows in that table are back to four columns. Left deliberately: the controller temp files are now per-run but still not cleaned up. Worth doing with ansible.builtin.tempfile and an always block, and it is a change to the shape of five task pairs rather than a fix to this PR's defects.

Review round addressed —
|
| Finding | Outcome |
|---|---|
dependency_patching audit claim is wrong |
Correct, and the most important one. The role is invoked by four playbooks. My greps covered api/*.py, services/*.py and two named playbooks — a scope that could not contain the answer — and I filed #17257 from it without verifying the negative. Corrected in the doc, the index row and the issue, to the narrower finding that survives: nothing runs those playbooks, so rollback is reachable only by hand |
| Resolve the controller source dir before filtering | Fixed. The filter used bare {{ code_source_dir }} while the copy applied a fallback, so a role without it copies fine and fails to filter. Same expression at all four sites now. It cannot be hoisted into a role default — a templated default referencing autobot.base_dir is what broke shard 9 earlier in this PR |
| Compare the complete manifest reference | Fixed. It compared only the tail after the last }}, so a copy rooted at one variable and a filter rooted at another matched. Whole resolved path now |
| Add executable contrast fixtures | Fixed. Two fixtures with answers known by construction. Worth noting the first version of that guard picked the redirect target, whose tail is .txt, so it passed against anything — found by mutation, not by reading |
| Regex splits a markdown table row | Fixed. Pipes escaped; all rows back to four columns |
Use ai_stack_requirements_src for the copy too |
Won't fix — the shape is forced. #14272 reads the copy's src basename, so it must end in a literal filename; #14809 allows the task file exactly one ai-stack/requirements-ai.txt, so the filter must use a variable. Neither side can take the other's form, and a change here re-breaks one of them — I did exactly that earlier in this PR. The real risk is drift under an override, which is now pinned by repo_tests/ai_stack_manifest_agreement_17242_test.py |
| Replace hard-coded controller temp paths | Deferred, deliberately. They are now per-run rather than per-host, which closes the collision. Cleanup via ansible.builtin.tempfile and an always block is a change to the shape of five task pairs, not a fix to a defect this PR introduced |
Two of these — the false audit claim and the vacuous tail comparison — were things no check in this repo could have caught. Both came from review.
Two items from the independent pre-merge review, both non-blocking, both done here rather than deferred since the files are new in this diff. The count was wrong again. The doc said patch-dependencies.yml invokes dependency_patching "four times"; it is five, at lines 63/75/87/99/111. I produced that number with a grep piped through `head -4`, which truncated the output -- and wrote it inside the paragraph correcting an earlier wrong claim about the same role, whose whole point is that a narrow instrument's empty or partial answer must not be read as the full one. Third time today a truncated measurement produced a wrong number. Corrected in the doc and in #17257. glob_declared_guards caught SyntaxError but not ValueError, which ast.parse raises on a null byte in the record. That propagates out of main(), and tools/git-hooks/pre-push treats a non-zero exit from the selector as "this push is NOT verified" -- so every push would be blocked, the exact opposite of this helper's contract. Now catches both, and main()'s read_text is wrapped against OSError and UnicodeDecodeError for the same reason. Verified: a record with a null byte returns {} and the real record still yields 27 globs.

…times (#17257) Review caught that my correction was also false. The claim has now been wrong in three successive forms and I am withdrawing it rather than narrowing it a fourth time. #17257 is closed as not-a-defect. The role is fully wired: five role invocations in patch-dependencies.yml plus three more playbooks; ansible/deploy.sh runs both dependency playbooks behind --patch-dependencies / --patch-dependencies-check / --rollback-dependencies (deploy.sh:359-388, :491-493, :646-649); and autobot-backend/api/settings.py:213 is an admin route that triggers patch-dependencies.yml as a Celery task. Each wrong version came from a grep whose scope could not contain the answer: 1. "invoked by nothing" -- api/*.py, services/*.py and two named playbooks. The four playbooks that call the role were outside that scope. I filed the issue from this. 2. "reachable only by hand" -- grep -rn with an alternation. grep treats | as a LITERAL without -E, so it matched nothing for a reason unrelated to the question. A broken instrument's silence, read as absence. 3. "four times" -- a grep piped through head -4. It is five. The paragraph now records the verified references and how the readings failed, because the method is the part worth keeping. The one true observation -- update-all-nodes.yml does not include the role -- reads as deliberate separation given a dedicated CLI and API route, and I am not asserting otherwise on the evidence I have.
The citation gate flagged deploy.sh:359 as ambiguous -- several files share that name -- in the very paragraph I had just written about verifying references properly. Qualified to autobot-slm-backend/ansible/deploy.sh. 34/34 resolve.

…ucturally (#4835, #17254) Merged main in (brings #17241's doc-index fix and the 6509 floor), then three rounds of fixes. CI shard 6 -- impact_endpoint_test patched get_code_collection, which this PR renames. Updated to the new accessor, and its stub now answers count(), because #17254 added an empty-graph check the old object() stub could not satisfy. Added the test for that behaviour: an empty graph must report indexed: false, since 'nothing calls this' and 'nothing has been indexed' are opposite answers. Review, Major -- the dispatch was a bare asyncio.create_task whose handle was discarded. The loop keeps only a weak reference, so the task can be collected mid-flight with its exception nowhere to surface and the status row stuck at 'running'. Now fire_and_forget. This code was pre-existing and harmless while unreachable; giving it a route is what made it matter. The dispatch moved into knowledge_code_indexing.py rather than growing the route module: that file sits exactly at the 1445 ceiling I lowered it to earlier, and a grandfathered file may not grow. Caller is one line again, file back to 1445. Review, Minor -- my own guard checked the decorator by scanning text, so a commented-out @router.post would have read as a live route: the same false-pass shape the guard exists to catch, one level down. Now an ast walk for a router .post decorator attached to index_code, with two fixtures whose answers are known by construction. Floors, both failing by exactly one file, both re-pinned to population minus growth after measuring rather than extrapolating: hooks-path-override 6509 -> 6511 (population 6911 = 6880 globbed + 31 extensionless shell scripts, enumerated directly) prompt-injection-strict 2949 -> 2950 (population 3250 non-test backend .py) Raising a reach floor is the stricter direction; a size ceiling may only come down, which is why a module split was the answer there and a re-pin is here.

Thinking Path
A two-host provisioning run reported "3 hosts failed" on a deployment that has two hosts.
That count is unreachable, which is what made the report worth distrusting rather than acting on.
Pulling the thread found two independent defects: the summary was lying about what failed, and
underneath it one real failure that aborts every host except the manager.
The log settled both. Ansible's own recap for that run:
failed=1 ignored=2. Ansible had it right; the summary threw the distinction away and reportedthree failures on one host as three hosts. Two of the three were the designed first-run
bootstrap path, which is
ignore_errors: trueprecisely because a host with nothing deployed yethas no marker to read.
The one real failure was
rc=127—build-filtered-requirements.sh: No such file or directory.code_sourceis the controller's git checkout and nothing syncs it to a node. The taskexecuted a script out of it on the target. It passed for as long as the manager was the only
backend host, because there the controller and the target are the same machine, and aborted the
first time a second host joined the group.
A scan of all 336 ansible YAML files found five more of the same shape. Three are in the builtin
updater, so this blocks updates on remote nodes, not only first provisioning.
What Changed
#17240 — the reporting defect (
services/ansible_utils.py)_failure_was_ignoredskips afatal:that ansible followed with...ignoring. Bounded at 40lines and stopped by a result boundary, so one task's ignored failure is never attributed to
another's.
when they differ, so wording is unchanged wherever it was already correct.
#17242 — the backend abort
Generated on the controller via
delegate_to, reading the manifest fromcode_sourcerather thanfrom the target, with the result written into the backend tree. Carrying it in a registered
variable also removes
/tmp/requirements-filtered.txt— a fixed name in a world-writabledirectory that every host would have collided on the moment this task moved to the controller.
Delegating alone would have traded one bug for a racier one.
#17243 — four more of the same shape
roles/ai-stack/tasks/main.ymlupdate-all-nodes.ymlPlay 2, ×3 pip stepsconstraints/shared.txtis staged onto the node; the constraint points at the local copyroles/_shared/tasks/record_slm_deployed_commit.ymlsync_deletions.yml, which has always delegated the identicalrev-parsePlay 1 (
hosts: slm_server) keeps itscode_sourcereference. The manager has it, and anearly version of this change repointed it too — which would have broken a task that was never
broken. Caught by re-deriving each reference's play scope instead of trusting a global replace.
#17244 — WSL2 locality
backend_ai_stack_hostasked only "is this WSL2", never "is the AI stack on this node". Itssibling twelve lines below has always asked
role_ai_stack_active; the two disagreed. Now it askstoo. Behaviour is unchanged whenever the stack is not on this node, which is the case #3503 fixed.
Verification
CI does not execute Ansible, so none of the deploy changes are observable in CI before a fleet
node hits them. That is exactly why they survived green runs. What was verified here:
ruffon both Python files-c constraintsreference re-derived by play scoperepo_tests/ansible_code_source_delegation_17243_test.pyfails when a target-side executingmodule reads
code_sourcewithoutdelegate_to, exempting controller/manager plays by scope,not by name, so a task that moves into a fleet-wide play stops being exempt automatically. It
carries a reach floor, so a walk that stops matching fails instead of passing vacuously.
For #17240, four tests were added that each fail against the old code. The pre-existing
test_multiple_failuresstructurally cannot catch either defect: it uses two hosts with onefailure each, so the two counts coincide and the conflated variable reads correct.
I did not run the suite locally — CI is the authority on tests here, and codebase code is not
executed against the live install.
What this PR cannot prove
Three of these four issues have an acceptance criterion this PR cannot meet: verification on a
multi-host topology. A single-node run cannot reproduce any of the
code_sourcedefects,because there the manager is the only target — that coincidence is the bug. So only #17240, whose
criteria are fully code-and-test verifiable, is closed here. The three deploy issues stay open for
host evidence rather than being closed on a merge.
#17245 (297 literal install-root paths) is deliberately not included. Its own criteria require
classifying each site as must-template or legitimately-literal, and a blind replace would risk
systemd units and log paths. It belongs in its own change.
